Hi everybody,
I'm having a rather exotic problem at the moment. Trying to connect to JBoss MQ
from a remote client, I succeed when I don't want to.
Some test code may make this clearer:
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL,
"jnp://mafaws01:1099"
);
env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
Context context = new InitialContext(env);
Queue queue = (Queue)context.lookup("queue/A");
System.out.println("Found queue: " + queue);
QueueConnectionFactory connectionFactory =
(QueueConnectionFactory)context.lookup("ConnectionFactory");
System.out.println("Found factory: " + connectionFactory);
This works fine when JBoss is up and running on the server mafaws01. But to my
amazement it also works when I've stopped JBoss! The output below is what I
get in that case. Apparently the NamingContext object fails to connect to the
naming service but still hands me back the factory and queue registered in the
JNDI tree, whereas I would prefer that it fails miserably... By the way, if I
change the JNDI names to something not found in JNDI, I don't get a factory and
queue.

Are JNDI names and stubs somehow cached locally? Does anybody know how to
disable this behaviour? Or is there away of checking whether the
connectionFactory is really only a disconnected stub?

Using Tomcat but need to do more? Need to support web services, security?
